  • Legend Help Needed

    It's good to be back. I got a new laptop and lost my login password. So I have not been on in a long time.
    For those of you that PM'ed me, my sincere apology, if you want to try again I will get back to you.
    Now the reason of the post:
    My friend bought a Miller Legend #KK226352 LP gas 4014 hrs.
    We got it started ran fine with no load, with the leads on DC it would barely run 1/8 6010.
    The motor lugged way down, I could make it run a bead but it was a chore and it did not matter what range the selector was in or the fine tune.
    I switched it to AC 70-105 setting fine tune #5 and it welded fair (6011), and the motor was way less labored but did not sound happy.
    I had a Legend years ago and it welded smooth and with ease. (Someone stole my Pickup, welder, air compressor, tools and all.)
    The welder it self looks real good, the paint is not faded, no dents or scratches, the decals are peeling off, but that's it.

    Now the Question: Why will it not weld in DC mode?
    Why is the motor so labored?
    Thank you in advance.
    Good Luck,
    Bob Miller

    Has the unit been sitting unused for a long period of time?

      I believe the welder was sitting for a long time. Also the nuts where the cable lugs attach did not look like they used.

      I'll think it was used as a generator. Or who ever attached the cables made sure not to turn the nuts over and scratch up both sides.

      Good Luck,

        That’s a fair amount of hours on a gas motor. As a rule of thumb, a gas motor is said to have around 5000 hours of longevity.
        For a machine that’s been sitting unused, I would check the brushes and ensure their not stuck and not completely worn out. I’f the brushes check out, then shine up the slip rings. Then check weld performance again.
